Industrial Screw Driving Datasets

Overview

This repository contains a collection of real-world industrial screw driving datasets, designed to support research in manufacturing process monitoring, anomaly detection, and quality control. Each dataset represents different aspects and challenges of automated screw driving operations, with a focus on natural process variations and degradation patterns.

Dataset Collection

The datasets were collected from operational industrial environments, specifically from automated screw driving stations used in manufacturing. Each scenario investigates specific mechanical phenomena that can occur during industrial screw driving operations:

Currently Available Datasets:

1. S01_thread-degradation

• Focus: Investigation of thread degradation through repeated fastening
• Samples: 5,000 screw operations (4,089 normal, 911 faulty)
• Features: Natural degradation patterns, no artificial error induction
• Equipment: Delta PT 40x12 screws, thermoplastic components
• Process: 25 cycles per location, two locations per workpiece
• First published in: HICSS 2024 (West & Deuse, 2024)

2. S02_surface-friction

• Focus: Surface friction effects on screw driving operations
• Samples: 12,500 screw operations (9,512 normal, 2,988 faulty)
• Features: Eight distinct surface conditions (baseline to mechanical damage)
• Equipment: Delta PT 40x12 screws, thermoplastic components, surface treatment materials
• Process: 25 cycles per location, two locations per workpiece
• First published in: CIE51 2024 (West & Deuse, 2024)

Upcoming Datasets:

3. S03_screw-error-collection-1 (recorded but unpublished)

• Focus: Varius manipulations of the screw driving process

Access and Citation

These datasets are provided under an open-access license to support research and development in manufacturing analytics. When using any of these datasets, please cite the corresponding publication as detailed in each dataset's README file. 

Related Tools

We recommend using our library PyScrew to load and prepare the data. However, the the datasets can be processed using standard JSON and CSV processing libraries. Common data analysis and machine learning frameworks may be used for the analysis. The .tar file provided all information required for each scenario.
